[0002] Ore pulp conductivity refers to the conductivity of electrolyte solution in ore pulp, and is an important physical quantity for measuring ion concentration and conductivity performance in ore pulp.The size of conductivity is closely related to the dissolved solid content, ion type and concentration in ore pulp.In mineral processing and beneficiation process, the change of ore pulp conductivity can reflect the chemical properties and process state of ore pulp.

[0003] Ore pulp conductivity is usually measured by conductivity meter, by inserting electrode into ore pulp, and measuring the conductivity between electrodes using alternating current signal.The measurement principle is based on Ohm's law, and the conductivity is calculated by known electrode constant and measured conductivity value.Common measurement methods include: electrode type measurement: directly contact ore pulp by electrode to measure its conductivity.This method is simple and direct, but electrode is easily contaminated by impurities in ore pulp, affecting measurement accuracy;electromagnetic induction type measurement: using electromagnetic induction principle, non-contact measurement of ore pulp conductivity is realized.This method avoids electrode contamination problem, and is suitable for high conductivity strong electrolyte solution.Measuring ore pulp conductivity is of great significance in mineral processing and beneficiation process: process control: by real-time monitoring of ore pulp conductivity, acidity, alkalinity or ion concentration in ore pulp can be indirectly reflected, so as to realize accurate control of leaching, flotation and other processes.Quality monitoring: the change of conductivity can reflect the content of impurities or the dissolution of minerals in ore pulp, which helps to optimize process parameters and improve product quality.Environmental monitoring: measurement of ore pulp conductivity can also be used to monitor the corrosion of ore pulp, to protect equipment from corrosion.

[0060] Specifically, the principle of the utility model is:

[0061] Preparation and assembly of the device:

[0062] Preparation of the ore pulp container: the ore pulp container is a conical structure with an open top, and its interior is used for containing ore pulp. The inner side wall of the container is pasted with multiple replaceable films, and the shape of the film is consistent with the shape of the inner side wall of the container, ensuring tight fitting. The film is divided into upper and lower parts, and a notch extending from top to bottom is arranged at the middle part, and the notch penetrates the side wall of the film;

[0063] Installation of the conductivity sensor: the conductivity sensor is located in the interior of the ore pulp container and is inserted into the container through the notch to directly contact with the ore pulp. The sensor is connected with the top of the container through threads, ensuring firm installation and sealing. The top of the sensor is provided with a cover body, and the inner side wall of the cover body is provided with a thread recess adapted to the thread protrusion on the top of the ore pulp container, ensuring the tightness of the connection;

[0064] Fixing and protection of the film: the material of the film is polytetrafluoroethylene film, and the side close to the inner wall of the container is coated with epoxy resin adhesive, which is used for firmly pasting the film on the inner wall of the container to prevent ore pulp leakage or seepage. The bottom of the film is provided with an arched tear handle for conveniently replacing the film;

[0065] Loading and measuring of the ore pulp: loading of the ore pulp: the ore pulp is poured into the container through the upper opening of the ore pulp container. Since the film is tightly fitted with the inner wall of the container, the ore pulp cannot seep into the space between the film and the container, thereby protecting the inner wall of the container from corrosion or wear;

[0066] Conductivity measurement: the conductivity sensor is inserted into the ore pulp and directly contacts with the ore pulp through the notch. The sensor measures the conductivity of the ore pulp in real time and transmits the signal to the external measuring device or control system. The design of the notch ensures smooth flow of the ore pulp and avoids accumulation around the sensor, thereby improving the accuracy and stability of the measurement;

The shape of the film matches the inner wall of the container, further optimizing the flow characteristics of the slurry, ensuring uniform distribution of the slurry in the container.

[0068] Maintenance and replacement of the device: Replace the film: When the film needs to be replaced due to wear or corrosion, tear the film off the inner wall of the container by pulling the handle. Since the film is divided into upper and lower parts, and the gap runs through the side wall of the film, the replacement process is simple and fast, and it will not be difficult to operate due to the overall adhesion;

[0069] Cleaning and maintenance: Since the film closely matches the inner wall of the container, slurry is less likely to accumulate between the film and the container, making the cleaning process easier. After replacing the film, the container can be cleaned to ensure the cleanliness and hygiene of the device;

[0070] Maintenance of the sensor: The conductivity sensor is fixed to the top of the container by screw connection, which is convenient for disassembly and replacement. The maintenance of the sensor includes regular calibration and cleaning to ensure the accuracy of the measurement.
